Application filed May 25,

To all whom t may concern Be it known that LAss ENGs'rRoM, citizen of the United States of America, residing at Seattle, in the county of King and State of Washington, has invented certain new and useful Improvements in Sanding Devices for Automobiles, of which the fol` lowing is a specification.

This invention relates to an improvement in sanding devices for automobiles or similar vehicles, whereby in the operation of the brake pedal or other control element, sand is delivered onto the surface over which the vehicle is traveling immediately in front of the rear wheels, thereby providing the desired traction.

The invention comprehends sand receptacles supported on the chassis immediately in front of the rear wheels and movable so that they may be positioned for lilling when desired. The receptacles are provided with valves which are normally closed and adapted through suitable connections to be opened 4 in the movement of the brake pedal, so that upon operation of said pedal, an appropriate quantity of sand will be delivered to and scattered over the surface of the ground immediately in front of the rear wheels.

In the drawings:

Fig. 1 is a partial plan of a chassis illustrating the application of the improved sanding device thereto.

Fig. 2 is an enlarged section on line 2-2 of Fig. 1.

Fig. 3 is a sectional detail showing connection between the valve operating mechanism and thebrake pedal.

The improved sanding device comprises duplicate sanding receptacles 1 and 2, which on their upper front and rear edges are formed with flanges 3 to slidably cooperate with angle brackets 4 rigidly secured to hangers 5 depending from the frame bars of the chassis. The sand receptacles which preferably have their forward walls 6 rearwardly inclined to direct the sand toward a discharge outlet 7 in the bottom ofsuch receptacles are connected one to another by transverse bars 8, the receptacles being of course of comparatively narrow width, and through the connecting bars 8 adapted for simultaneous movement upon the brackets 4. The tops of the receptacles may be fully open or are preferably closed and formed 1922. Serial No. 563,577.

with filling openings 9, whereby the sand may be introduced at will. A valve v10 is arranged to close each o utlet 7, said valve being or" lever form and pivotally supported at 12 upon straps 13 secured to the receptacle, the valve levers having forwardly eX- tending operating projections 14 and offsets 15 connected by springs '16 to the receptacle, the springs operating to normally hold the valves in closed position, as will be obvious from Fig. 2 of the drawings. A. shaft 17 is supported in bearing brackets 18 secured to the underside of the main frame bars of the chassis, and this shaft has lateral arms 19 secured thereto inline with thefreceptacle valves, which arms are through rod or exible connectors 2O secured to the valve lever projections 14. Obviously through r0- tation of the shaft, the valves 10 may be simultaneously operated to permit discharge of the sand through the receptacle outlets. The shaft 17 is provided with an intermediate lateral arm 21 to which is connected the rear end of a rod 22. The forward end of this rod extends upwardly through the floor of the vehicle adjacent l the board 28, the rod being suitably bent to provide for this mounting. The for ward end of the rod is guided in a plate 24 secured to the toe board and is suitablv provided with a pivotally supported dog 25,

which in one position is adapted to be engaged by the foot piece 26 of the brake lever 27. The dog however, is adapted to be moved out of operative position so that the brake lever may be moved without correspondingly operating the rod 22.

The receptacles as previously described are mounted for sliding movement and hence they may be successively arranged beyond the chassis frame bar for filling and then positioned so that the discharge opening T is immediately in front of the particular rear wheel 28. Then in the application o the brake pedal, assuming the dog 25 to be in operative position, the outlets 7 of the receptacles are temporarily open and sand scattered on the surface in front of the rear wheels. A. deliector 29 is secured to the bottom of each receptacle to yscatter the sand discharged from the opening over the comparatively wide area with respect to the tread of the wheel. lt is apparent that when moving over a slippery surface where lll."-

receptacles in slidalole coopera-tion .with kthe v chassis, a valve for each receptacle, and means `for simultaneously operating the valves.

2. A sanding device for automobiles and thelike, including reCBptacles connected for similar movement, means for supporting the receptacles in slidable cooperation With the f chassis, a valve for each receptacle, `and means for simultaneously eoperating the valve in the actuation of the brake pedal.

3. A sanding device for .automobiles l,and the like, including Lreceptacles connected for similar movement, means for supporting the receptacles in slidable 4cooperation with the chassis, avalve for each receptacle, means for simultaneously operating ,the yalves in the actuation ofthe brake pedal, and means on the receptacles for spreading the ma-l terial delivered therefrom. l

4. A sanding device forzautomohiles, in cluding' s and receptacles, valves 'controlling outlets therefrom, a rod for simultaneously operating lthe valves, a dog pivotally mounted upon the rod and adapted in one :position to interpose a projection in the path of movement of the brake pedal, and another position to permit free movement or" the brake pedal with respect to the rod.

5. A sanding device for automobiles, including sand receptacles, means for slidahly mounting the receptacles, rods ,connecting the receptacles to each other, valves controlling` outlets therefrom, `a rod Vfor simultaneously operating the valves, a dog `pivotally mounted upon the rod and adapted in one position to interpose a projection .in the path of movement of the brake pedal, and another positionxto permit free movement o'l the brake pedal With respect to the rod.
